Dietary intake is the most important determinant of over- or undernutrition, but it is not the only influence on an individual's nutritional status. A series of extrinsic environmental factors or intrinsic clinical or physiological disorders can alter the absorption, retention, utilization, and integrity of nutrients. These give origin to secondary malnutrition states. Primary (dietary origin) and secondary (environmental, pathological) factors often combine within the same individuals. From a public health perspective, the goal is to implement broad policies and programs that increase the availability of specific nutrients imperiled by the local environmental problems, e.g., iron in hookworm infested areas, while addressing the primary diseases. In the clinical setting, management requires diagnosing and managing the underlying pathological states interfering with nutritional health while providing compensatory measures to correct secondary nutritional imbalances.
